Man City frustrated
Meanwhile, former Manchester City boss Mark Hughes frustrated his old club as his confident Stoke side held them to a goalless draw at the Britannia Stadium.
The Potters were unable to secure a third successive English Premier League win but produced another encouraging performance as they continue to develop under new manager Hughes.
Stoke forward Jonathan Walters spurned one of the best chances of the game when he headed wide from a superb Charlie Adam cross in the first half.
